• #30559 — Acoustic Sound Reinforcement for a Cathedral — Представитель этого кластера

  Как мы озвучили храм — Ena_lab

  Смысл: The main idea is the technical application of acoustic modeling and linear array technology to overcome extreme reverberation in a religious building, ensuring speech intelligibility without destroying the traditional atmospheric sound of a cathedral.

  Engineering experts used EASE modeling and Bose linear arrays to solve severe echo and speech intelligibility issues in a newly built cathedral.

• #17259 — Sound System Installation at Spartak Stadium

  Как мы озвучивали стадион «Спартака» — Ena_lab

  Смысл: The main idea is to describe the engineering challenges and practical execution of equipping a large sports stadium with a high-performance sound system that meets both entertainment and safety (evacuation) standards.

  A technical case study on the design, installation, and calibration of the complex sound and emergency notification system at Spartak's Otkritie Arena.

• #16353 — Automating Musical Chord Detection via Spectral Analysis

  Про автоматизацию подбора аккордов — t0mm

  Смысл: The text describes an engineering journey to build a tool that extracts musical chords from audio. It highlights that simple frequency analysis is insufficient due to real-world noise and musical complexity, requiring a combination of signal processing, probabilistic classification, and Markov-based transition modeling to achieve usable results.

  The author develops a chord detection system using FFT, chromagrams, and Markov Chains to overcome the noise and complexity of real audio recordings.

• #4978 — 3D-Printed Acoustic Metamaterials for Noise Reduction

  Разработан метод шумоизоляции, гасящий до 94% шумов — рассказываем, как он работает — Audioman

  Смысл: The text describes a breakthrough in sound insulation using 3D-printed acoustic metamaterials based on Fano resonance. It explains how a specific spiral shape can cancel noise while allowing air to flow, compares this to other metamaterial research, and discusses the potential for improving urban living environments.

  Engineers have developed a 3D-printed 'breathable' plastic ring using Fano resonance that can block up to 94% of noise.
